本病为良性骨肿瘤,其特征为骨质破坏进展迅速,常并发病理性骨折及脊髓麻痹。作者报导手术及活检证实的4例动脉瘤样骨囊肿行放射治疗,取得良好效果。例1,女性,15岁,主诉步行障碍,瘤灶部位第10胸椎。术后行~(60)钴照射,前、后二野,每次剂景150～200rad,总剂景7850rad/54日,CER 为2058.5reu,观察15年6个月无复发。例2,女性,12岁,主诉腰背疼痛,两下肢运动障碍,瘤灶部位第1腰椎。术后行6MV 直线加速器X 线照射,前、后二野,每次剂量200 rad,总剂量4000rad/33日,CRE1330reu,观察5年2个月,无复发。
The disease is a benign bone tumor. It is characterized by a rapid progression of bone destruction, often associated with a rational fracture and spinal cord paralysis. The authors reported that 4 cases of aneurysmal bone cyst confirmed by surgery and biopsy were treated with radiotherapy and achieved good results. Case 1, female, 15 years old, complained of walking disorder, 10th thoracic vertebrae at the tumor site. After 60 ~ cobalt irradiation, before and after the two fields, each dose of 150 ~ 200rad, the total dose of 7850rad/54 days, CER was 2058.5reu, observed 15 months and 6 months without recurrence. Case 2, female, 12 years old, complained of low back pain, two lower extremities dyskinesia, and first lumbar vertebrae at the tumor site. After the operation, a 6MV linear accelerator was irradiated with X-rays. The front and back fields were dosed with 200 rad each time. The total dose was 4000rad/33 days, and CRE1330reu was observed for 5 years and 2 months without recurrence.
